After so much skimming, I didn't see...Did they used a more powerful pump? That's all the difference with such a large radiator. If the liquid can barely move through the system...They won't really see the temps they should.

Good point. A radiator the size of a car is gonna need one good pump or 2+ smaller pumps.
